Title:
METHOD OF IDENTIFYING A PROTOCOL GIVING RISE TO A DATA FLOW
Document Type and Number:
WIPO Patent Application WO/2011/114060
Kind Code:
A3
Abstract:
Method of identifying a protocol at the origin of a data flow. The method of identifying a protocol giving rise to a packet flow comprises the following steps: - a capture (102) of the flow of the protocol to be identified, - statistical classification of the flow, comprising an extraction of the classification parameters and a comparison of the classification parameters with statistical models constructed during a learning phase. The statistical classification comprises: - a first phase (108) of global statistical classification; and - a step (120) of synthesis of the results of the first and second classification phases (108, 110) so as to identify the protocol giving rise to the flow.
